Problem
Charlotte: A 60-year-old woman was fit and well until late in the summer she was out tending to her lovely tulip garden when she was stung on the back of her right hand by a pesky wasp. This was nothing new, unfortunately as she had been stung a couple times in the last two weeks. With in minutes after this sting Charlotte fell to the ground and looked as though she was becoming pale/grayish and was gasping for air. After five minutes it was getting worse, but likely a neighbor doctor rushed over and administered an epinephrine shot, which provided support until the ambulance could arrive.
i. Which antibodies and cells are involved in this allergic reaction, how do they cause it, and how does it lead to anaphylaxis? Why didn't this happen on the first stings?
ii. How does anaphylaxis impact the body and how did the epinephrine help counteract that?
iii. The image below was taken of her blood smear. What is a blood smear? Identify the leukocyte below and explain why it was present.
